I want to query to get the details from the command line - django

Question

In The Models.py file (I have this codebase)
class Person(models.Model):
sex_choices = (
('Male', 'Male'),
('Female', 'Female')
)
martial_choices = (
('Single', 'Single'),
('Married', 'Married'),
('Divorce', 'Divorce'),
('Widowed', 'Widowed')
)
name = models.CharField(max_length=200)
sex = models.CharField(choices=sex_choices, max_length=50)
martial_status = models.CharField(choices=martial_choices, max_length=50)
age = models.IntegerField()
def __str__(self):
return self.name
class DetailsOfEducationQualification(models.Model):
type_choice = (
("Government", "Government"),
("Private", "Private"),
("Anganwadi Center", "Anganwadi Center"),
)
education_proximity_choice = (
("0-5", '0-5km'),
('5-10', '5-10km'),
('10+', 'Above 10km'),
('Outside the state', 'Outside the state'),
)
person = models.ForeignKey(Person, on_delete=models.CASCADE)
course_class = models.CharField(max_length=50, blank=True)
type_of_education_sector = models.CharField(choices=type_choice, max_length=50, blank=True)
education_facility_proximity = models.CharField(choices=education_proximity_choice, max_length=50, blank=True)
In The Admin.py file (I have this)
from .models import (
Person, DetailsOfEducationQualification
)
class DetailsOfEducationQualificationInline(admin.TabularInline):
model = DetailsOfEducationQualification
extra = 0
class PersonAdmin(admin.ModelAdmin):
fieldsets = [
(
'Personal Information', {
'fields':[
'name', 'sex', 'age', 'martial_status'
]
}
),
]
inlines = [
DetailsOfEducationQualificationInline
]
In query shell, I want to get the person 'course_class' since the DetailsOfEducationQualification model is related to Person:
like in he query:
person = Person.objects.get(id=1)
person.course_class
this code gets an error, saying person does not have the attribute...
How do I access the DetailsOfEducationQualification date from the Person model?

Answer 1

course_class is an attribute of DetailsOfEducationQualification class, and not an attribute of Person class,
so you won't be able to access it from a person object.
detail = DetailsOfEducationQualification.objects.get(id=1)
detail.course_class
the above code will return the course_class of DetailsOfEducationQualification with id 1.
if you want to access course_class from a Person object,
then you can use
person = Person.objects.get(id=1)
person.detailsofeducationqualification_set.first().course_class
person.detailsofeducationqualification_set is the Queryset of all DetailsOfEducationQualification objects that has person with id 1 as foreign key.
and, person.detailsofeducationqualification_set.first() will be the first element of the queryset.
hope it helps.
